Farm crews reported the smell of diesel to Emergency Management B.C. just before 5 a.m. PT, according to an official report.

The federal fisheries department says the spill was caused by a diesel pump that was left on overnight.

Just after 2 p.m., Courtney Bransfield, emergency program co-ordinator for the Mount Waddington Regional District, said the spill was “contained to the farm’s fish pens” and that absorbents to soak up the spill were in place.
